M/TMBau/nah UNITED STATES WILLIAM N. BAUMAN, OF GLEIBURNE, TEXAS.

CURTAIN-POLE CLAMP.

Specification of Letters Patent.

Application filed May 1, 1917. Serial No. 165,772. a

To all whom it may concern Be it known that I, IVILLIAM'N. BAUMAN, a citizen of the United States, residing at Cleburne, in the county of Johnson and State of Texas, have invented certain new and useful Improvements in Curtain-Pole Clamps; and I do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisrinvention relates to improvements in a curtain pole clamp.

The prime object is to provide a device of this nature particularly adapted for mounting on a shade or curtain supporting bracket, and one having a slidable clamping sleeve mounting a nut against rotation, and coopcrating with a screw associated with the sleeve and bracket.

Additional objects and advantages will appear from the description of the present embodiment hereinafter following taken in connection with the illustration thereof in accompanying drawings.

In said drawings Figure 1 is a front elevation of a window frame utilizing shade or curtain supporting brackets employing my improvement;

Figure 2 is a view particularly showing my improvement in side elevation and in connection with a supporting bracket and window frame;

Figure 3 is a perspective view particularly illustrating one of said supporting brackets;

Figure 4 is a fragmentary view of one of said supporting brackets having its clamping sleeve in section to illustrate details, and

Figure 5 is a cross sectional view on the line 55 of Figure 4.

Like numerals of reference designate cor responding parts in the different figures of the drawings.

Referring more particularly to the drawings, the numeral 1 designates a window frame of ordinary construction. The hangers or brackets are designated 2 and a plurality thereof are shown as mounted from window frame 1 and as supporting a usual shade or curtain pole 3. Said brackets are fastened in place in any suitable manner andgenerally may be of any approved construction. Each bracket has an arm 11 forming a clamping jaw which has its upper surface cut away to provide a notch 12. A vertical arm 13 is provided on each bracket which has its upper end curved forwardly as at 14% and terminating in a collar 15. A clamping sleeve 16 is closed at one end and provided therethrough with a central opening 17 in which a bolt or screw 18 is disposed. The shank of said bolt is screw threaded as at 19. Said sleeve 16 is provided with an elongated longitudinally extending slot 20 through which said curved portion 14 extends to re- .movably and slidably secure the clamping sleeve thereto. A nut 21 is carried by the bolt, held against rotation by the sleeve 16, and engages the lower end of the collar 15 so as to facilitate the raising or lowering of the sleeve 16 relatively to the arm 11.

The lower end of the sleeve 16 has a notch 22 to cooperate with the notch 12 of the arm to firmly clamp said curtain bolt 3. V

In use, the pole 3 or its equivalent is disposed in the notches 12 and 22. Thereafter, the screw or bolt 18 is turned which forces the sleeve 16 downwardly into tight clamping engagement with said pole 3. lVhen the pole is to be released, the screw or bolt is turnedlin the reverse direction, so that the head Wlll disengage the closed upper end of the sleeve, to enable the sleeve to be raisedto release the pole.

I claim Patented Jan. 31, 1922. v

A pole clamp including a mounting arm having a collar, a nut-abutting the arm, a clamplng sleeve surrounding the nut and mountlng it agalnst rotation, the collar being disposed within the clamping sleeve, said clamping sleeve having an elongated slot through which said arm extends and a closed end, and an adjusting screw passingthrough said closed end and the collar in threaded engagement with the nut. V

In testimony whereof I affix my signaturein presence of two witnesses.
